Held since December 2009 — that's 16 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 93 m² it's 17.3% larger than the typical home in the postcode (79 m² median across 22 EPCs). On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £134,000 is 35.4% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£99/sq ft) was about 19.6% below the postcode norm.
